IMPROVEMENT IN` LUBRICATQRS FOR STEAMCHESTS The Scheduie referred to in these Letters Patent and. makingV part of the same.

T0 all whom tt may conce/m,

Be' it known that I, HENRY C. DE LAND, of the city of Syracuse', in thecounrty of Onondaga and State of N ew York, have invented a new and improved Method ot' 'Lubricating the Steam-Chests and Cylinders of Steam-Engines and Locomotives, while in motion, with 4Suet and Tallow'or Lard; and' I do hereby declare that the following is ai'ull and exact description thereof', reference being had to the accompanying drawing and to the letters of reference marked thereon.

Myinvention relatesvnto 'devices for iling or lubri-l cating parts-of a steam-engine,- and consists in so constructing and arranging' the part-s of an oil-cup that, when it is supplied with lubricating material and so connected to the steam-chest of an vengine as to communicate' therewith, it will lubricate the parts of the same automatically, asl hereinafter explained.

ln the drawin'g.

vFigure l is a `side elevation of the device, with the cup and itsl interior tubes shown in section.

Figure 2 is a longitudinal section of a part, detached.

In constructing this devicea cup, B, is made of any size and form desired,l and out of any suitable metal.

It is provided with a neck, O, having an opening through it communicating with the interior, and also with an adjustable head, A, which, by means of a screw-thread, screws into and may be set at any desired height in an opening iu the upper side ot' said cup, which opening also commui'iicates'with its interior', all as clearly shown in iig. l.

'lhe neck -O is provided with a stop-cock, D, for opening and lclosing the passage through it, and also at its lower end with a screw-thread, G, for connecting it with the steam-chest of an engine.

The head or plug A is made of a different metal from the cupB in order to make a perfectly steamtight connection. A

Within the cup B a tube, F, perforated or slotted along its sides, is securely attached by'means of a screw-thread, or in any other suitable manner, at b, so as to form a continuation of the passage through vthe neck O. 'Its length .is such that its upper end may terminate near the center of the chamber of the oil-cup.

Over this tube F is\placed another tube, E, so

as to slide freely thereon. This. tube has its upper end closed or capped, and is of the proper length to allow it, when down, to cover the entire 'length of the tube F, and, consequently, the slots or perforations therein. Its form is clearly showd in figs. 1 and 2.

The device thus constructed is attached to and so as 'to communicate with the steam-chest of an` engine by means of the screw-thread-G on itsI lower end. l

The capped sliding tube E is placed upon the stationary tube F, and the interior of the cup is filled `with tallow, snet',`lax1l,'or .other suitable lubricating material, and. the head'o'r plug A is then screwed in and adjusted' ls'o as to limit the height to which the sliding tube E` may rise, as desired.-

The operation of the device is as follows:

When the engine is'in 'mot-ion the-cock Dis. turned so as to admit the steam from the steam-chest into the tube F.

As the piston in the cylinder of the engine moves iu one" direction the steam will rush from the. steam-- chest up the tube Fand raise the tube E till it strikes against the lower end ot' the head or plug A, and when 'the tube Eis so raised will pass through the slots or perforations in the tube F and fill thechamber of the cup', and melt or liquidize the lubricating material therein; 'and as'the pistou moves y inthe opposite direction it will draw the steam and lubricating material'now mixed with it out of the chamber of the oil-cup and down into the steamchest, and, at 'the same time, the sliding tube E will drop to its original position, so` as to prevent too great a supply ot' the lubricating material from passing from the cup.

The' supply may be regulated by adjusting the head or plug Aso as to allow'a greater or lesser movement of the sliding tube E, as desired.

The lubricating material thus drawn with the steam from the chamber oi' the oil-cup into the steam-chest finds its way to the different parts ofthe' machinery, i/uto which the steam may force or carryit, and lubricates them. a

It will thus be seen that the sliding tube E becomes automatic in its movement, and that the distribution of the lubricating material is also automatic and continuous with the continuons motion of the engine.

While any form of' cup may be used, one having a spherical o r globular form is preferred, as having the greatest strength. i

The lengths of the tubes E and F 'should besuch that, however high the tube E 'may beallowed to rise when arranged yto operate, its lower lend may still be upon the end of the tube F. l

In this way a cheap, simple, and effective means is provided of automatically liquidizi'ng the lubricating material in an oil-cup, and drawing the same therefrom in any desired quantities to the steam-chest of' lan engine, for lubricating its 'machineryl- Having thus described my invention, tion with the slotted or perforated tube lF, whenl con- What I claim is str uoted. mid arranged to' be. operated substantially as w 1.
